The One O'Clock Lab Band® is the premier performing ensemble of the University of North Texas jazz studies program.

With an unprecedented seven Grammy Award® nominations (one or more per decade and under every director since the 70s: Lab ‘75, Lab ‘76, Lab ‘89, Lab ‘91, Lab 2009, Lab 2015) from the library of over eighty critically acclaimed recordings to date, the One O’Clock Lab Band is noted for exceptional individual musicianship and tight ensemble performance.

One O'Clock Lab Band® maintains its uncanny aptitude for both timeliness and timelessness with the November 19 release of Lab 2021 (North Texas Jazz). The latest installment in an annual series that has continued since 1967, the album features six original student compositions, five of them by members of the 20-piece student ensemble, as well as two standards with new student-penned arrangements. In addition, it offers new work by two of UNT's jazz faculty members and prolific Lab Band contributors: Grammy-nominated composer Rich DeRosa, the school's Director of Jazz Composition and Arranging, and Alan Baylock, the acclaimed big band veteran (Airmen of Note, Alan Baylock Jazz Orchestra) and director of the One O'Clock Lab Band.
